It appears that nothing in this project uses more than 24 volts, and if a safety agency approved step-down transformer is used to produce 24 VAC for the solenoid valves, the user will never be exposed to more than 24 V RMS. As such, the "high voltage" disclaimer could be removed. In North America, 24 volts or less is classed as "Safety Extra Low Voltage".

Although I commend you for your ingenuity, Melitta makes a Pour-Over 1-Cup Brew Cone, designed to be set on top of a mug or cup. They use Melitta #1 disposable paper filters, into which one would put a tablespoon or two of ground coffee and then slowly pour boiling water over it. These gadgets have been around for decades, but the improved version has a cut-away section near the bottom, so one can see into the mug to prevent over-filling. If I were working in an office, I'd keep one of these in my desk drawer.Not being much of a coffee connoisseur, in the absence of proper paper coffee filters, I would risk using a piece of paper towel. One can also buy "permanent" filters in various sizes, although I'm not sure if anyone makes one equivalent to the Melitta #1 paper filte...see more »Although I commend you for your ingenuity, Melitta makes a Pour-Over 1-Cup Brew Cone, designed to be set on top of a mug or cup.

If you're going to feed your temperature readings to a weather service, a home-built weather station would need to be carefully vetted and tested against one built in the traditional way. The original Stevenson screens were made of wood, painted white and were in use for more than a century. Some stations have recently been set up with vinyl Stevenson screens, and it is not clear if their performance is identical to the original wood screens. There is a suspicion that part of the "global warming" phenomenon may not be real and may be due to differences in materials used in thermometer housings. If you're building this screen for your own use, though, it will most likely to the trick for gathering consistent local relative readings.

Most commercial baits use a chemical called metaldehyde to kill the slugs and snails. It breaks down into harmless components and does not poison the soil and environment. Although the baits are rather overpriced for what they do, if you can procure a supply of metaldehyde, a white powder in pure form, a small amount will go a long way and is quite economical, even compared to cheap beer.

Why mess around with a phone? Just install the SDHC card in a card reader on a Linux desktop or laptop machine. The card reader can be built-in or connected via USB. You can then do <i>anything</i> on the card — create, delete, move files and directories and change file permissions.

I think the original stencil font, which you called "boring", is more legible than the version you picked. If these numbers are for the benefit of emergency vehicles, delivery services, etc., a font should be chosen for maximum legibility, at distances up to 30 meters/100 feet.

While it is true that curb numbers wouldn't be visible when the streets and curbs are covered with snow, they are still useful the rest of the year.

Whether one lives in an area with snow or not shouldn't make any difference. The concrete needs to be dry and relatively warm to be painted, so this kind of a project wouldn't be feasible during rainy, snowy or freezing periods.
